Single Row Cylindrial Roller Bearings NJ200 Series

Basic Info

Model No.: NJ200 Series

Rolling Body: Roller Bearings

The Number of Rows: Single

Product Description

Single Row Cylindrial Roller Bearings NJ200 have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.

Cylindrial Roller Bearings NJ200 Series are designed to have heavy radial load- carrying capacity; rolling elements are ground to provide maximum contact with the raceway and are precisely crowned to avoid edge loading due to any shaft misalignments. These bearings are commonly separable and easy to mount and dismount.
